My stepsister wanted to join the track team, so she asked me for some pointers. I started by stretching her legs, but she was so flexible that her shorts ripped, and I could see her wet pussy! Then, her ass was sore, so I told her that the best way to recover was to swallow some cum because she could get some protein out of it. I didn’t think she’d listen to me, but she sucked my cock dry! After helping her for a while, her leggings ripped because her ass was finally getting bigger and bigger. When that happened, I knew it was time to claim my reward. I helped her build that body, so it’s only fair that I enjoy it too. Even her pussy will be sore after everything I have planned for her.
